[3] Acknowledging the benefits of vertical integration, Gonzalez-Frausto established his own distillery, La Primavera, and spent the next 40 years improving his craft.

[4] In 1983, Marco Cedano returned to Don Julio to work as an engineer, where he served as Master Distiller and Distillery Manager of Tequila.

Diageo signed a joint venture in with Casa Cuervo in 2003, selling a 50 per cent stake in Don Julio for 78 million.

[6] It was distributed in the United States by Diageo, under licensing from its patent holder, Tequila Don Julio, Sociedad Anónima de Capital Variable, Jalisco, Mexico,[7] but sold worldwide.

[9] Don Julio Gonzalez-Frausto Estrada was born on 7 January 1925 in Atotonilco, Jalisco, where today's main facility is located.

By 1951, with the brand Tres Magueyes, he was on a path that would later become Tequila Don Julio in its different variants: Blanco, Reposado, Añejo, 70, 1942 and Real.

[10][non-primary source needed] The agave for Don Julio's Tequila is grown in the highland area of Atotonilco on the family estate.

After the fermentation process is complete it results in a sweet, slight alcoholic agave beer which is then put into stills where it is distilled to become tequila.
